Overview: This guide provides a comparison of Dandy zirconia crown and bridge offerings, including material characteristics and clinical preparation guidelines
Dandy Zirconia Product Offerings
Dandy provides three types of zirconia restorations, each designed for specific clinical strengths and aesthetic needs.
Aesthetic Zirconia: These are full-contour anterior or posterior crowns. Aesthetic zirconia offers greater translucency than monolithic zirconia but less than Porcelain Fused to Zirconia (PFZ).
Monolithic Zirconia: These are posterior crowns designed for patients with bruxism and bridges up to an entire arch. Monolithic zirconia is the most opaque material selection.
Porcelain Fused to Zirconia (PFZ): These single- to full-arch restorations are ideal for cases involving deep shoulder preparation or dark stumps requiring high translucency.
Material Characteristics and Specifications
The following table compares the physical properties of Aesthetic, Monolithic, and PFZ zirconia materials.
